An hourly rate reveals little on its own: an experienced engineer at a premium rate can be less expensive in the end than two juniors who need supervision and rework. Ask as well which roles are billed: coordination, testing, DevOps and design are real work, but these should be visible in the estimate.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;The number in the proposal is never the total cost.
